image text in transcribed
The breaking strengths of cables produced by a certain manufacturer have a mean, u, of 1875 pounds, and a standard deviation of 100 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 45 newlyr manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1882 pounds. Assume that the population is normally distributed. Can we support, at the 0.1 level of significance, the claim that the mean breaking strength has increased? {Assume that the standard deviation has not changed.) Perform a onetailed test. Then ll in the table below. (3am,r your intermediate computations to at least three decimal places, and round your responses as specied in the table. The null hypothesis: Ho : The alternative hypothesis: H] : The type oftest statistic: (Choose one) V The value of the test statistic: (Round to at least three decimal places.) The pvalue: (Round to at least three decimal places.) Can we support the claim that the mean breaking strength has increased? 0 YES 0 No
